This paper reviews the literature on the provision of in-service education of teachers (INSET) in the area of education for multicultural society. It traces the changing emphasis from a concern with the amount and take-up of INSET to a more qualitative analysis of the process and impact of INSET. The paper begins by updating an earlier contribution on the period immediately before and after the publication of the Swann Report. Developments in school-focused work, especially those with an action research dimension, are noted. Specific reference is then made to racism awareness training and also the particular needs of 'all white' areas. Finally the training needs of teacher trainers and ethnic minority teachers are considered.
